Abstract

A display apparatus includes a substrate (100), a display area disposed on the substrate and including pixels, a non-display area disposed outside the display area, a first power supply voltage line (10) including a first conductive layer(10a) disposed in the non-display area and a second conductive layer (10b) disposed on the first conductive layer, a second power supply voltage line (20) disposed in the non-display area and including a third conductive layer (20a) spaced apart from the first conductive layer and a fourth conductive layer (20b) disposed on the third conductive layer, a first dam portion (110) surrounding the display area and overlapping the second power supply voltage line, a second dam portion (120) disposed adjacent to the first dam portion, and a cladding layer covering a first end portion of the fourth conductive layer formed in a direction intersecting a direction in which the first and second dam portions extend.
